It could be anything from the single board controller up to the scanner pwb's.
Hi JD Power,
Thank you for using the Support Forum. If this is only occurring on copies please make sure the document feeder is closed when scanning the image. Power the machine off wait 30 seconds and power back on. If it still happens perform a software reset. If that does not fix the problem please consider contacting your support centre for further assistance.
WC7835- only occurs when copying. Anyone ever seen this? I can actually see a little text under the banding.
Thanx
